LIQUID msrnnsnn.

Application filed May 16,

. ments in Liquid Dispensers, of which the following is a specification.

My invention relates particularly to a dispensing apparatus intended for dispensing such materials as catsup, which is generally a rather heavy liquid and which does not flow freely. f

The object of my invention is to provide means whereby a measured individual charge of catsup maybe trapped and then positively ejected from a container.

Another object is to provide a dispenser of this character which may be connected to the usual standard catsup containers.

A further object is to provide simple and reliable means for effecting the trapping and ejection of an individual charge.

A further object is to provide a dispenser which is of simple and inexpensive construction and which will be reliable in operation. I

A further object is to provide a dispenser which may be supported above the average level of the liquid, to permit'drainage there from into the liquid container.

My invention comprises those novel parts and combinations thereof which. are shown in the accompanying drawings, described in the specification and particularly defined by the claims terminating the same.

In the accompanying drawings I have shown my invention in the form which is now preferred by me. I

Figure 1 is an axial section through a catsup container and my dispenser showing the latter secured upon the container.

Figure 2 is an enlarged section similar to Figure 1, showing a detail of the dispenser.

Figure 3 is a section on line 3.3 of Figure 2.

Figure 4 is an enlarged sectionon line 44 of Figure 1, showing a portion of the dispenser. a

' I secure a tube 1, which to distinguish it from other tubes, maybe called the'linner tube, within suitableImounting or securing means, such as the 10 which maybe screwed or otherwise secured u'po'nthe end of theordinary catsup bottle or container The u 6l e d i wa d i em t e cap .0

within the neck' of the bottle, but preferably not to the bottom of the bottle, and also preferably extends for ashort. distance outward of the cap. It isdivided betweenits ends by a diaphragmll and a delivery spout 1,505,511 PATENT OFFICE.

12 communicateswith the space beneath the diaphragm 11, being shown herein as extending through the diaphragm. A lateral delivery outlet 13 is formed on the uppere nd of the spout12. i

At its inward end, being that endwithin the bottle and inward of the diaphragm,-'the tube 1 is ported, ports 14 being shown.

Through. these ports. communication is.

established with the interior of the .container C. An outer tube 2' is 'slidabl'e upon the inner tube 1, and this tube likewise is provided with ports 24 which are normally in registry with the ports 14:. When moved lengthwise, however, over the inner tube 1, the outer tube 2 will close the ports 14 and thusa charge of material will be trapped within the inward portion'ofthe inner tube. A plunger 3 is movable through the inner tubel, To effect movement of the plunger I have shown a stem 31 which projects outward through the diaphragm 11 and which has secured toits outward end a flexible ten sion member This tension member passes over several guides 33, which reverse it in direction and then again reverse it into its originaldirection. Its free end is secured to a, rod 34 guided in a fixed guide 35 and having a push button 36, preferably likewise guided upon a guide 37. Movement of the push buttonv 36 will effect movement of the plunger 33 in the same direction, to eject a charge. The plunger is returned to normalposition by the action of a spring 37 bearing upon a collar 38 secured tothe outward end of the stem 31. F

I provide means actuatively connecting the plunger 3 and the outer tube 2 whereby upon movement of the plunger 3 in the direction to eject a charge, the outer tube 2 is automatically moved in a direction to close the ports 14:, and vice versa. The means which'I have shown for accomplishing this comprise a bar 30, preferably toothed upon oppositesides, and projecting from the rear side of the plunger to which it is conne cted, and 1 a pair of levers" whichare pivoted between their "ends'upon the inward end er. the inner 'sleeve' 1 or'upon' ears projecting therefrom. The inner end of the 'lever'sare toengag'e theteeth the container is still held in inverted position the push button 36 is moved upward in the position shown in Figure 1, or downward in the pouring position of the con tainer... This initiates movement of the plunger 3 through the flexible tension member 85 and the stem 31 in opposition to the spring 37.

At the beginning of this movement the levers 4 are in the position shown in Figure 1 and the ports 14 and 24 are in registry. The movement of the rack bar causes positive engagement of its teeth with the inner ends of the levers 4, and these are moved into the position shown in Figure 2. During this movement engagement of thepins 41 with the U-brackets 42 eifects movement of the outer tube 2 sufficiently to close the ports 14. When the ports 14 reach closed position the levers 4 reach such a position that they no longer engage the teeth of the bar 30 but act as ratchet pawls to permit continued movement ofthe bar 30 and of the plunger 3. I I

Continued movement of the plunger 3 through the closed trap formed within the tube 1 expels the charge from the trap through the delivery spout 12. When sufficient of the material has been expelled. the push button 36 is released and the action of the spring 37- effects a return of all parts to. their normal position. At the beginning of the return movement the inner ends of the levers 4 again engage with the teeth of the bar 30 and the outer tube 2 is reversed in position thereby, and its ports 24 are brought into registry with the ports 14 of the inner tube.

. VVhatI claim as my invention is:

- 1. A dispensing apparatus including a pair of members having a plurality of axially spaced ports, and relatively axially movable through a short distance to form a closed trap for an individual charge of the material to be dispensed, and a separate ejector; movable through such trap through a greater distance to expel the material.
